public HierarchicalGraph()

Method Detail

clear

public void clear()

Description copied from interface: Graph

Clears the Graph.

After this method, the graph tables are almost in the same state as if it had been created afresh except it contains the same columns as before but they are all cleared.

Specified by:

clear in interface Graph

Overrides:

clear in class DefaultGraph

addVertex

public int addVertex()

Description copied from class: DefaultGraph

Adds a new vertex to the graph.

Specified by:

addVertex in interface Graph

Overrides:

addVertex in class DefaultGraph

Returns:

the vertex number.

addVertex

public int addVertex(int parent)

removeVertex

public void removeVertex(int vertex)

Description copied from interface: Graph

Removes the specified vertex from the graph.

Specified by:

removeVertex in interface Graph

Overrides:

removeVertex in class DefaultGraph

Parameters:

vertex - the vertex to remove

getTree

public Tree getTree()

getVerticesCount

public int getVerticesCount()

Description copied from class: DefaultGraph

Returns the number of vertices in the graph

Specified by:

getVerticesCount in interface Graph

Overrides:

getVerticesCount in class DefaultGraph

Returns:

The number of vertices in the graph.

vertexIterator

public RowIterator vertexIterator()

Description copied from interface: Graph

Returns an iterator over the vertices of the graph.

Specified by:

vertexIterator in interface Graph

Overrides:

vertexIterator in class DefaultGraph

Returns:

an iterator over the vertices of the graph
